Perceived usefulness of eco-driving assistance systems in Europe

Assessing the perceived usefulness of eco-driving assistance systems is of high interest for system developers and researchers in the development stage of such systems. This applies especially to systems that try to influence the driver´s behaviour in everyday situations and generating their greatest benefit if regularly used. This study presents results of a survey simultaneously conducted in 11 European countries with more than 5000 respondents aiming at collecting needs and requirements for future eco-driving assistance systems. Such systems have the potential of changing driving behaviour in the long run for supporting a more fuel-efficient driving and reducing emissions caused by motorised traffic. Three different driver assistance systems are considered covering inefficiencies in pre-trip, on-trip and post-trip situations. Each system is assessed according to the factors of perceived usefulness, the expected environmental impact and the user´s willingness to pay for it. The study will show that in general car drivers welcome the deployment of eco-driving assistance systems and rate them as useful. It likewise demonstrates that the acceptance of additional costs for the user is very low.
